tBeacon 0.54

Changes:

Close proximity search mode was rename to Proximity mode. The beacon will report received signal strength with every call. It was found, that this search mode is more efficient not only on close distances, but on far distances too. Three beeps are still there for you, oldschool guys. :)

Entering Proximity mode was simplified a lot. No more following the rhythm, you can do it more relaxed.

External LiPo battery monitoring. The beacon can substitute a Low Voltage Buzzer! There are two thresholds: WARNING and CRITICAL. The beacon will notify both with radio and with LED/buzzer.

The beacon will beep decently every 30 minutes. Just in case it was forgotten to turn off.

You can tune the buzzer frequency in order to obtain a loud resonant sound. There are corresponding testing buttons in the configurator.

Every new tBeacon get a new bootloader, which allows to use an UART without DTR pin.

Fixed a number of bugs. Including that nasty bug with power of the last beep.

NOTE: when upgrading from previous releases, all settings will be reset to default! You'll have to at least calibrate the frequency.Also note that some defaults are changed!
